The `infrastructure-upgrade` repository. This contains `relayer-registry` contracts, and is intended to upgrade Tornado infrastructure for various functionalities and goals.
Please note that deployments only work via Hardhat, and only with the specified configuration. It seems that Forge outputs different bytecode than Etherscan, and that Hardhat also outputs for some contracts different bytecode than Etherscan if optimizations are not disabled.
`yarn build` has to execute a script to modify a single Uniswap dependency because of a stupid version pragma, if you check it out (in `script/setup.sh`) you will just notice that it goes into the file mentioned and changes the version pragma from 0.7.0 to 0.6.12. That is all of the changes needed.
